Product family
Air filter, oil filter, air-oil separator and precision elements for screw, rotary and reciprocating air compressors — direct replacements for Kaeser, Atlas Copco, Ingersoll Rand, Sullair, Fusheng and other mainstream compressor platforms.
Primary and secondary air intake elements in pleated paper, polyester fabric and laminated media for screw and rotary compressors.
















Spin-on and cartridge lube oil elements with fiberglass or paper media, matched to original part numbers.












Coalescing separator elements that keep oil carry-over below the compressor manufacturer limit.

















Fine and precision grade elements for compressed air downstream filtration, vacuum pumps and special compressor models.












Engineering notes
Compressed-air filtration is three separate duties, not one. The intake element protects the airend from atmospheric dust; the lube oil element keeps the oil clean; the air-oil separator keeps oil carry-over out of the discharge line. Each is specified differently, and each fails differently.
The family covers those three duties, plus precision and fine elements for downstream compressed-air treatment. Every model page states the part number, dimension, end-cap style and filtration rating we hold for it, so an element is matched against the one currently in the machine rather than against a catalogue picture.
Match outer diameter, height, end-cap and whether a secondary safety element is fitted. Paper, polyester and laminated media are all held.
Spin-on and cartridge types. Match thread or cartridge geometry, bypass arrangement and micron rating; media is fiberglass or resin-impregnated paper.
Match bowl geometry, gasket and return-line arrangement. Separation performance is set by the media grade, not by the housing.
Downstream coalescing and fine filtration, with ratings stated per model down to 0.01 μm where the construction supports it.
Brand names are used only to describe the platform an element is compatible with. JIANASH is an independent manufacturer of replacement filter elements and is not affiliated with, endorsed by or authorised by any of the original equipment manufacturers listed.
Send the compressor model and serial number, the element dimensions — outer diameter, height, inner diameter — and photographs of both end caps. We cross-reference to the platform and quote the closest match; if nothing in the catalogue matches, we cut to the drawing.
No. They are aftermarket replacement elements cross-referenced to the platform. We are not affiliated with, endorsed by or authorised by the original equipment manufacturers; brand names are used only to describe compatibility.
The air filter sits on the intake side and removes atmospheric dust before the airend. The separator sits after the airend in the oil circuit and removes oil mist from the compressed air. They are not interchangeable, even when they look similar.
Yes. Air filter, oil filter and separator are quoted as a set for one service interval and consolidated into a single shipment, which is the usual arrangement for annual maintenance contracts.
Common models ship from stock. Custom or low-volume items are quoted with a firm lead time once the drawing or sample is confirmed. State quantity and destination when asking.
